Water Based Nanofluids: A Computational Study on Temperature Distribution in a Pipe Flow

Abstract

Fluid containing nanometer-sized particles (i.e. nanoparticles) is known as nanofluid. Three different nanofluids flowing in a pipe with heat source at the inlet and sink in the walls are studied. The base fluid is water. 20 nm size nano-particle Al2O3 is mixed with base fluid with volume concentrations of 0.1%, 0.2% and 0.5%. Simulation is done using ANSYS Workbench 17.1. The result shows correlation between concentration of nanoparticle and temperature gradient at the outlet of the pipe.
